9o is GoSublime's command-shell, press ctrl+9 or super+9 activate it.

It has two basic concepts: commands and actions.

Commands

Type # (hash/number sign/pound sign [space]) to begin a command sequence e.g. # help', then press enter to execute it.

Actions

Filename and other actionable text are highlighted (usually bold). Place the cursor over these areas and press ctrl+dot,ctrl+g' (or super+dot,super+g on OS X) to open the corresponding file. Alternatively, press ctrl+shift', (or super+shift on OS X) and left-click.

Command modes

9o has two command modes: sh and 9o.

In sh mode your commands are passed as-is without interpretation directly to your shell. e.g. you might want to use special features of your shell like piping (sh echo 123 | filter-cmd)

For all other commands, the command line is split by spaces, taking quoted args into consideration and then environment variables in each argument are expanded (as well as ~/ which is short-hand for your $HOME directory) and then the command is executed.

If the command is not found(not a 9o builtin), it's treated as-if it was run via sh

Environment Variables

In 9o mode, environment variables of the form $NAME and ${NAME} are supported.

The following variables are defined for each command you execute. These will override any variable of the same name that might've been inherited from your shell or the Sublime Text environment. Additionally, these variables will be defined within the initial environment of all commands executed through 9o, so they should appear inside commands run through your shell. Please be aware that your shell might override these variables with its own, epecilly in the case of $PWD

  • $_wd (or $PWD): the absolute path to the current working directory

  • $_fn: the absolute path to the current active file. If the file hasn't been saved, this will be an empty string.

  • $_nm: the base name of the current active file. If the file hasn't been saved, this will be n empty string

9o's commands

  • help: Present documentation for 9o and its supported commands

  • build: build the current package

  • run: build the current package. If it's a regular package run its tests otherwise(package main) execute it. e.g. run or run -flag1 -flag2=abc

  • replay: like run but attempts to cancel any active executions before running

  • go: run the go command e.g. go help

  • clear: clears the output panel

  • tskill: lists or cancels active tasks. type tskill to show a palette containing a list of active tasks and their summary and cancel them where possible

    type tskill [TASK ID] to cancel the task. The task is represented by #TASK_ID. (you will be prompted with an ok/cancel dialog to confirm the action)

      [ tskill t1 | done ]
  	kill t1: yes

    the following aliases can be used in place of task ids: tskill replay kill the last instance of the replay command tskill go kill the last instance of the go command go run etc. note, however that this may fail to actually kill the executable being run by go run

  • settings: list settings as seen by GoSublime. type settings to get a listing of all settings. type setting [NAME1] [NAME2] ... to the value of the listed names

  • env: list environment variables as seen/generated by GoSublime. type env to get a listing of all environment vars usable by GoSublime. type env [NAME1] [NAME2] ... to the value of the listed names

  • share: share the active view's content on play.golang.org

  • hist: manage command history type hist to list all historical commands type hist erase to erase all historical commands

  • cd: change directory type cd to cd to the directory of the current file (like ctrl+9 does) type cd ~/go to cd to the go directory in your home directory type cd $GOROOT/src/pkg/fmt to cd the src/pkg/fmt in your GOROOT

  • which: locate a command type which to list all builtins type which cmd1 cmd2... to locate the listed commands

  • echo: output the specified arguments type echo $_fn to output the path to the current file (if it has a name on-disk)

Executing commands

When you run a command e.g. replay, its line is replaced with the command followed by and hour glass and a new prompt is initialised. When the command completes a its output is printed and the hour glass replaced with a summary.

[ /go ] # replay
	|
	v
[ replay ⌛ ]
[ /go ] #
	|
	v
[ replay | done: 2.987ms ]
	hello world
[ /go ] #

Command History

In the 9o autocompletion menu, old commands are listed in the (reversed) order they were last executed. They are prefixed with a carret(^) e.g. ^1 replay. In addition to being able to autocomplete them, you can also expand them by their alias(without execution). To do so, type the alias and press [enter] e.g.

[ /go ] # ^1

is replaced with:

[ /go ] # replay

To expand and execute an old command by its alias, use two carrets e.g.

[ /go ] # ^^1

executes the last command:

[ `replay` | done: 2.557ms ]
	hello world
